Here is a full taxonomy of the family Euphorbiaceae, according to the most recent molecular research. This complex family previously comprised five subfamilies: the Acalyphoideae, the Crotonoideae, the Euphorbioideae, the Phyllanthoideae and the Oldfieldioideae. The first three are uni-ovulate families, and the last two are bi-ovulate.
Now the Euphorbiaceae has been split into five families: The three uni-ovulate subfamilies have become the Euphorbiaceae in the strict sense, with the tribe Galearieae in the Acalyphoideae forming the most of the family Pandaceae. Part of the bi-ovulate subfamily Phyllanthoideae has become the family Phyllanthaceae, with the tribe Drypeteae as family Putranjivaceae. The other bi-ovulate subfamily Oldfieldioideae has become the Picrodendraceae.
Plants of the World Online places genus Phyllanoa in Euphorbiaceae.[1] Hayden et al. place it in Violaceae.[2]
